658 DR. J. E. GRAY ON NEW TORTOISES. [June 23, 
ment. I keep them distinct because it is possible the adult may be 
different, as Dr. Leith assures me that he never saw a Tortoise in 
Sindh like the adult 7. marginatus from Greece.

TEsTUDO HORSFIELDII, Gray, Cat. Sh. Rept. p. 7, t. 1, has been 
referred to the genus Homopus, and noticed under the name of Ho- 
mopus burnesit by Blyth, because it has four claws on each foot ; 
but it has not the alveolar surface of the jaws ; and the general form 
of the shell is very like that of the genera Testudo and Peltastes, 
and very unlike that of the true Homopus; therefore I have found 
it necessary to form for it a new genus named Testudinella. 
TESTUDINELLA. 
Head covered with large thin plates on the nose and crown, with 
small polygonal scales over the orbits, nape, and temples. Horny 
sheath of the upper jaw rather high, with a deep broad notch in the 
upper edge of the front for the nose-disk, keeled in front. The 
dental edge acute, with a notch on each side and an acute keeled 
central lobe. Lower jaw rather strong, with a sharp denticulated 
dental edge and a rounded prominence in front. Alveolar surface 
with a small pit in front and a deep groove parallel to the whole 
outer margin; of the lower jaw with a distinct and narrow ridge on 
the inside, extending nearly the whole length of the outer margin of 
the jaw. Skull witha slender, short, scarcely prominent zygomatic 
arch, much narrower than the orbit or the tympanum. Thorax 
hemispherical, with a distinct nuchal shield. The fore legs covered 
with thick, large, triangular scales. Toes 4.4.

In the Proe. Zool. Soc. 1869, p. 189, I described two distinct 
species of this genus, divided into two sections. I have lately re- 
ceived from M. A. Sallé a very distinct species belonging to the first
